Application filed December 89, 1924. Serial 170. 758,656.

To all whom it may Be it known that I, ARTHUR A-,PAGE, a citizen of the United States, and resident of Racine, in .the county of Racine and State I of Wisconsin, have invented new and useful Impi'ovements in Means for and Methods of aking Plaster Casts of Feet, of which the following is a. description, reference being had to the accompanying drawings,

which are a part of this specification.

This invention relates to improvements in the means for and method of making plaster casiisloi feeth uh 1 h dzf eop e wit pec 'ar y s a act or persons having foot ailments of tzn findit necessary to have shoes made to order to secure a perfect fit and a comfortable shoe and shoe-makers who cater to a trade of this character and make shoes to order, find it very desirable to take an impression of the 'persons foot and make a cast therefrom in order that they may take measurements directly from the cast whenmaking up the shoes. v y

15 It is, therefore, theprinci a1 object of the present invention to prov'i e a very simple and efi'ective device for and method of making plaster casts as abovementioned.

A further object of the invention is to so provide a device for making casts of feet which permits the removal of a persons foot therefrom 'witho'ut disturbing the impression taken."

A further object of the invention is to provide a deviceof the class described in which the mold can be immediately removed after an impression has been taken, in order to take another-impression.

rov'ide a device of the class described havmg a flat base, thereby making it very acces- "sible for operating.

A further object of the invention is to provide a device and method of the class described in which the material forming the mold can be easily broken or separated without injury to the foot cast to remove the same intact, the mold being preferably formed in three. sections an thereof being removable for lacquering.

A further object of the invention is to sections removed andthe completed cast of one section V A further object of the invention is to rovide a means for and method of 111 'ng plaster casts which is very simple, efiicient and inex nsive. Y

With t e above and other objects in view, the invention consists of the improved means for and method of making plaster casts of feet and its arts and combinations as set fgrth in the c aims, and all equivalents there- 0 In the accompanying drawi in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a side view of the box wherein the impressions are made and casts formed;

Fig. 2 is a rear endview thereof;

Fig. 3 is a plan view thereof;

- Fig. 4 is a view similar to- Fig. 2 with the ,back removed and the sides partially lowered.

Fi 5 is a erspective-view of'the device showing the rst ste in the process of tak ing an impression o afoot;

Fig. 6 is a perspective view showing the mold formed over afoot;

Fig. 7 is a perspective view showing the rear ofthe box removed, a side lowered, and p the rear section of the mold removed in order that the foot can 'be withdrawn from the device; 4

Fi 8 is a view similar to Fig. 7 only showing the parts replaced ready to have material poured thereinto to form afoot cast.

Fig. 9' is a longitudinal sectional view taken on line 9-9 of Fig. 10; v

' Fig. 10 is a cross sectionalview taken on line 10-10 of Fig. 9; and

Fig.11 is a view showing all of the mold a foot.

-Referring now mo're particularly to the v drawings, it will be seen that the numeral 12 indicates a box-like structure formed with a flat base 13, a front 14, a removable back 15, and hingedly connected sides 16. The inner ,end portions of the sides are recessed as at 17 and 18 to receive the front and back and the sides are arranged to fold outwardly and downwardly as shown in Figs.

4 and 7. The back is provided with looking devices 19 to engage complementary locking members formed onthe rear ends of the s des to normally hold the back 15 in positiomas shown 1n Figs. 1, 2 and 3. However, when the locking membersare disengaged, the back may be entirely removed,

. permit the separation of thereof. Metal as shown in Fig. 7.

When it is desired to' take the impression of a persons foot, the box is closed up and the bottom of the box is filled with a layer of plastic material, preferably laster of Paris, as indicated by the numera 21. The foot is then greased or covered with a coating to prevent adhesion and pressed into the base layer 21,- as shown in Fig. 5. A coating of some material to prevent the adhes on of the upper layer is spread upon the base layer. Divisions 22' of utty, clay or a similar material are then built up between the sides of the foot and the sides 16 of the box and when plastic material is again poured into the box to fill the same and cover the foot, said divisions 22 separate the rear portion 23 of the mold from the rest plates 24 are pushed into the forward part of the mold to facilitate separation of the same when desired.

The next step in the pre aration of '8.-

cast is shown in Fig. 7, and't e back of the box 15 isremoved and one side lowered. After this is done,- the plutty divisions 22 t e back portion 23 of the mold and said back portion is removed entirely to permit the withdrawal of the persons foot.

At this stage, the interior of the mold can be readily lacquered and otherwise prepared for the formation of the foot cast and then the parts are re-assembled, as shown m Fig. 8. Plaster of Paris or a suitable plastic material is then poured into the lacquered mold and allowed to' form therein, the shape of the mold being shown in Fi 9 and 10. After the cast has hardened t e backof the box is removed and the sides lowered aspreviously described. "Then, the

a rear ortion 2310f the mold is removed and the ront portion of the mold can be separated into sections 25 and 26 and removed, the metal plates 24 permittin easy so aration thereof. The complete cast 0 foot, desi ated 27, can be then removed, and it wil befound to be a true and accurate reproduction of'the persons foot.

Obviously all of the sections forming the mold can be quickl removed from the boxand the box can repared for taking another impression. Else, if several rsons are wa1tin an im ression of one oot can be taken and the mo d removed from the box and other impressions taken, the molds being filled and cast at a subsequent time. H

From the foregoing description it will be ,securing said bac 'mold, an

1,cae,sos f seen that the improved means for and method of forming casts of feet is both simple and novel and is well adapted for the pur ose set forth.

at I claim as my invention is: g 1. A device for making a cast of a foot, consisting of a box arran d to receive plastic material, said box having a removable back, 'lockinlg members for removably and hinged sides whereby formed plastic material within the box may be entirely removed or in art removed, an 'means insertable vertica y and transversely in and between said plastic material to permit easy separation of the same when formed into sections.

2. In a device for forming casts of feet, a box having a flat base, sides hinged thereto, a front and a removable rear, locking members for removably securing said rear portion, a layer of unformed plastic material covering said base and adapted to have a foot ressed thereinto, partmg material vertica ly and transversely disposed between portions of the box and a foot =positioned therein, and unformed plastic material filling said box above said lower layer and covering a foot, said last. mentioned plastic material being separably divided by said parting material and plates in the forward part of the mol to facilitate the separation of said mold.

3. The method of forming casts of feet which consists of providin a box-like device having a removable po ion, fillin the bottom of the device with a layer of p astic material, pressing a foot into said plastic material, so aratmg portions of the last mentioned p astic material by vertically and transversely disposed dividing means, coverin the foot with plastic material and then 'al owing the same to form, removing the removable portion of the device and a portion of the formed mold thereadjacent withdrawin the foot from thebox an mold throng the opening thus provided,'replacing the removed portions of the mold and box, (pouring plastic material into the tioned material to form.
